Abstract Optical communication gained popularity in past few years. Optical communication has many distinct advantages over copper cable based electronic communication. Optical switches are integral part of optical networks which are used for rerouting of packets and also plays important role in contention resolution of the packets. These switch uses fiber delay lines (FDLs) act as optical memory. In past analysis of the switch is done by considering loss, power and noise and finally bit error rate (BER); however dispersion was neglected which is an important parameter in high speed communication. In this paper, design analysis is done by considering dispersion compensation along with optical amplifier noise.

AbstractWe demonstrated a full duplex hybrid passive optical network and indoor optical wireless system employing coherent optical frequency division multiplexing. To accomplish reliable transmission in passive optical networks integrated visible-light communication (VLC), yellow light-emitting diode and infrared LED is used in downstream and upstream, respectively, for intra building network. In order to support high data rate, pulse-width reduction scheme based on dispersion compensation fiber is incorporated and system successfully covered the distance of 50 km. A data stream at the rate of 30 Gb/s is transmitted for each user out of eight users. VLC-supported users are catered with the bit rate of 1.87 Gb/s over 150 cm and in order to realize a low-cost system, visible and infrared LEDs are used in downlink and uplink, respectively.

Forward Error

In this paper, an overview of various types of error-correcting codes is present. Three generations of forward error correction methods used in optical communication systems are listed and described. Forward error correction schemes proposed for use in future high-speed optical networks can be found in the third generation of codes.

Abstract Due to the evolution of data centric applications demand for high speed data transfer and more bandwidth is increasing continuously. The unavailability of components like tunable wavelength converters (TWCs) restrict the transfer of parallel information using wavelength division multiplexing (WDM), therefore in the present scenario optical orthogonal frequency division multiplexing can be used. Moreover in optical communication narrow Gaussian pulses are transmitted, which spread with distance and leads to the broadening of the pulse and pulse peak power goes down and thus limits the system. In this paper a Soliton based optical communication system is proposed and its comparison with Gaussian pulse is presented and it has been found that soliton pulse has lesser bit error rate in comparison to Gaussian pulses.

Abstract The characteristics of all optical networks such as high speed, data carrying capacity and transparency make them suitable for emerged networks domain. This paper presents an overview of research challenges in the field of all optical communication networks. Various subdomains of an all optical system, for example device-level designs, communication technique-level designs and network-level designs have been extensively investigated and presented in this paper. Further, the related research issues under each category of these domains have been discussed. These issues constitute the basic criterion for further development in all optical domain.

New Generation

Optical switches (OS) are widely used for switching optical signals in optical networks. Parameters and technical characteristics of OS include its capacity, number of inputs and outputs, speed of transition from one state to another, optical losses during signal transmission in the channel (value of attenuation coefficient in “on” state) and switching obstacles or switch off (in “off” state) the value of the extinction coefficient) and so on. The article proposes a new design of a new generation 3D switch based on a comparative analysis with other optical switches to create a high-speed and efficient optical transition in optical networks. The working principle of the proposed 3D switch is explained and a new structural block diagram is developed. The efficiency probability of the elements ensuring the stable operation of the proposed optical switch was calculated, calculations were performed in the MATLAB environment, and graphs of the probability of unrejected operation of the device were constructed.
